Endangered marine and avian species face critical survival threats

Various endangered species are facing severe threats to their survival due to human activity and disease. In marine environments, the Vaquita porpoise, found only in the northern Gulf of California, is considered the world's most endangered marine mammal. With only about 10 individuals remaining, the population has plummeted from an estimated 600 in 1997, primarily due to entanglement in gillnets used for illegal totoaba fishing.

Sea turtles also face significant risks. Despite international protections under CITES, leatherback and other sea turtles remain threatened by illegal fishing, bycatch, habitat destruction, pollution, and coastal development. Artificial lighting on beaches has also been noted to hinder hatchlings from reaching the sea.

On land, avian influenza (H5N1) is threatening vulture populations globally. At least 16 of the 23 vulture species are currently endangered. The highly contagious virus has caused significant mortality among black vultures and turkey vultures in the United States and South America, as well as bearded vultures in Europe and various condor species in the Americas. Researchers note that vultures provide essential ecosystem services by consuming carcasses and limiting the spread of pathogens.
